This is an all computerized animation with a mix of rotoscope. Though the principle slow in and slow out was used often, it was most prominent in the dancing scenes. Some of the scenes using slow in and slow out where scenes with the two main characters walking or dancing, and with the dog's movements moving in and out of the scenes. One of the main parts of the animation where you can see slow in and slow out is during the last dancing scene. When she’s moving into the jump there are more frames, then during the jump, she moves slower because there’s fewer frames; than when she lands there are more frames. This is a simple example of slow in and slow out.
